Laparoscopy technique has caused a high impact in the surgical community. The success of this technology is the application of the surgical conventional practices to access in the abdominal cavity, with diagnostic and therapeutic purposes, with a minimum surgical intervention. This procedure has been used for biliary lithiasis, now it is an advanced procedure in several pathologies interventions; the reason is because surgical set of instruments has been improving. The base of laparoscopy procedure is the video surgery, which for nature needs the training of the surgeon and the knowledge of the set of instruments, as well as his advantages and his limitations.
The correct use of this technology prevents surgical problems and the correct knowledge of the instruments in every particular condition, avoids human operation mistakes. Additionally to all inherent problems in the use of the technology, an additional variable exists; the position of the image is displayed in a monitor, in a different position from the area of operation. This implies an additional training of the surgeon so that the surgical act has fluency and continuity.
The image is taken by an endocamera and projected in a monitor. The first barrier that the surgeon must overcome is the difference between the position of the image and the place of navigation of the instruments. If there is the possibility of projecting the image on the human body with the same characteristics of an open surgery, we can have closer this methodology over to the traditional surgeries, achieving the advantages of the video surgery over a virtual traditional surgery. With this new technological modification, the surgeon does not use the image of monitor and in his place he sees, in his visual field, the internal image of the abdomen like an open traditional surgery.
The training would centre on the use of the laparoscopy instruments and the surgeon will feel the sensation of being in a traditional operation, with consistent progress in his surgical skill. In order to obtain this objective, we can propose the use of the augmented reality technique, which allows having the human real body in the field of vision and the superposition of the internal image of the abdomen [4].
